elasticsearch基本CURD方法及示例

一.索引添加、删除、修改

• 添加语法

PUT /my_index
{
    "settings": { ... any settings ... },
    "mappings": {
        "type_one": { ... any mappings ... },
        "type_two": { ... any mappings ... },
        ...
    }
}

• 创建索引的示例

PUT /my_index
{
  "settings": {
    "number_of_shards": 1,
    "number_of_replicas": 0
  },
  "mappings": {
    "my_type": {
      "properties": {
        "my_field": {
          "type": "text"
        }
      }
    }
  }
}

或

curl -XPUT '192.168.127.98:9200/my_index?pretty' -d '{   "settings": {     "number_of_shards": 1,     "number_of_replicas": 0   },   "mappings": {     "my_type": {       "properties": {         "my_field": {           "type": "text"         }       }     }   } }'

• 查看所有索引

curl '192.168.127.98:9200/_cat/indices?v'

• 修改索引

PUT /my_index/_settings
{
    "number_of_replicas": 1
}

或

curl -XPUT '192.168.127.98:9200/my_index?pretty' -d '{"number_of_replicas": 1 }'

• 删除索引

DELETE /my_index
DELETE /index_one,index_two
DELETE /index_*
